<p>PURPOSE:To control a recording speed to a fixed value in no relation to the length of a recording paper conveying path by controlling the paper fed timing being based on information relation to the time required for conveying recording paper. CONSTITUTION:A paper feed unit group 30 is a different unit from a picture forming device main unit, having two or more paper feed units 30-1,.... Each paper feed unit 30-1 or the like is connected to a reference roller 19 of the picture forming device main unit by recording paper conveying routes 40-1,.... That is, the reference roller 19 provides a function introducing recording paper to a side of the picture forming device main unit, being placed in a reference position. Each paper feed unit 30-1 or the like feeds to a control unit 28 a data relating to the time required for conveying recording paper S1 or the like in the corresponding recording paper conveying route 40-1 or the like by communication. And the control unit 28 controls the paper feed timing of the recording paper by the above described data.</p> |
